geforce 4 TI4200 memory error?

Bought myself a soltek Geforce 4 TI4200 couple days ago. Installed the lastest nvidia detonator driver. When I go to my video display properties, it listed my card on board memory as 64meg instead of 128meg. But when i reboot my comp, there it listed my card as 128MEG. Anyone know the solution to this? And do i get any downgrade performace from this if it list 64meg in windows but 128meg in boot up.

I used to have that a problem on my 3D Prophet DDR-DVI ( GeForce 256 DDR ). It was a 32mb card & sometimes at bootup it would report 16mb. I never had performance problems because of that though. On the GeForce FAQ, I remember them saying it was because of defect memory chips.

Here's the advice they gave :

Q. I (occasionally or always) get less than 32MB of video RAM reported when I first switch on my PC. What's up?
Try slightly changing your FSB speed.

Make sure that you are using a powerful enough power supply. See the 'How powerful should my power supply be in order to use the GeForce? question for more information.

You can find a link for a BIOS that may fix this problem for the Creative Annihilator Pro in the 'Are there any newer Video BIOS upgrades for the Annihilator?' question.

You may want to replace the card even if this does help: this problem may also be a bad solder joint on one of the memory chips that causes problems occasionally or all the time.

k found my problem. I have 2 512kb memory stick, after i took out 1 of them window ME finaly show the card on board memory at 128MEG. Does that mean my ram is defected? Or window ME don't support 1gig of memory? Or could it be powersupply problem?
